I see the problem: you've added a 'data' handler right after you called the async mkdirp. This causes data to be released immediately. Remove that and you should be fine.

What node version are you using?

from busboy.

metd commented on August 20, 2024

node v0.10.16
expressjs 3.4.4
connect-busboy 0.0.1

may be problem is about synchronous or asynchronous,
when i use mkdirp in synchronous mode, it's work fine.
problem happened when i switch to asynchronous mode

This is my code.

var express = require('express');
var http = require('http');
var busboy = require('connect-busboy');
var fs = require('fs');
var mkdirp = require('mkdirp');
var path = require('path');
var inspect = require('util').inspect;

var app = express();

app.use(
    busboy(
    {
        limits : {
            fileSize : 10 * 1024 * 1024
        }
    }
));

app.get('/upload', function(req, res, next){
    res.send('<html><head></head><body>\
            <form method="POST" enctype="multipart/form-data">\
             <input type="text" name="textfield"><br />\
             <input type="file" name="filefield"><br />\
             <input type="submit">\
           </form>\
         </body></html>');
});

app.post('/upload', function(req, res, next){
    req.busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
        console.log('File [' + fieldname +']: filename: ' + filename + ', encoding: ' + encoding);

        var rootDir = path.dirname(require.main.filename);
        var uploadDir = 'media/photos';
        var saveTo = path.join(rootDir, uploadDir);

        mkdirp(saveTo, function(err) {
            if (err) {
                console.error(err);
                return next(err);
            } else {
                console.log('Save File..');
                saveTo = path.join(saveTo, path.basename(filename));
                file.pipe(fs.createWriteStream(saveTo));
            }
        });

        file.on('data', function(data) {
            console.log('File [' + fieldname + '] got ' + data.length
                    + ' bytes');
        });
        file.on('end', function() {
            console.log('File [' + fieldname + '] Finished');
        });

    });

    req.busboy.on('field', function(fieldname, val, valTruncated, keyTruncated) {
        console.log('Field [' + fieldname + ']: value: ' + inspect(val));
    });

    req.busboy.on('end', function() {
        console.log('Done parsing form!');
        res.send(200, 'OK');
    });

    req.pipe(req.busboy);
});


http.createServer(app).listen(4000);
